Good to know. I've been recommending Wes's book for a some time now to people new to data work in Python, but between the discussion here and the consistently high quality of Jake's blog posts and demos, I'll have to kee

Would you really argue that Bitcoin has "large scale adoption"? Most people aren't using it yet apart from cryptocurrency enthusiasts and currency speculators.

It's referring to https://en.wikipedia.org/wiki/Hype_cycle which is meant to describe the pattern of hype -> disillusionment -> eventual larger-scale adoption that often accompanies new technologies. Seems l

That's not really how antibiotic resistance develops: it happens at a population-level rather than an individual bacterium level. If, for example, you've got an antibiotic that messes with normal cell wall formation in a particula

Plane tickets have an odd setup in CC processing systems where it actually shows origin/destination in the transaction information itself. The only other similar example I've seen has been in payment processors like Square or Payp

This sort of thing shows up in lots of different pricing mechanisms. There's no structural reason why plane or train tickets should be cheap far in advance and then go up in price a lot as the departure date nears; it's just that

You're right - it's just pretty close. Presumably, most of their net assets are cash based on that though with other stuff thrown in.

Cash. It's the (mostly) the cumulative sum of revenue - expenses.

By "child investments", they mean investments in children, not children-as-investments. In other words, they're suggesting that not only are children in these disadvantaged situations starting off in a worse place, but each a

Cochrane ( http://www.cochrane.org/ ) is often a good aggregator for medicine-related subjects. Unfortunately, it doesn't look like they've got anything good for this one -- just a few things relating to caffeine an

Interestingly, it gives the wrong times for the "caramelise" spelling, but the correct time for "caramelize."

Yes, it would reduce the search space three-fold (the 4th mechanism uses the same stored hash as the 1st), and your suggestion of different salts would prevent that since each password variant would need a separate search. Still, the differ

Your "90/10 all the way down" explanation is a really good one that I may borrow. I often tell people new to the field that because there's more in the overall field of data science that anyone can know, everyone feels l

Even if you know the truth behind a statement like that, it's hard to read something that earnest and not have an initial eye roll in response. As someone who doesn't know the YC team's motivations, it's nice to know tha

A fair point for sure, which is actually one of the reasons why I do tend to recommend the book. ML and stats are generally the more flashy and well-known parts of data science, and so I've found that people new to the field often don&

Would just throw an extra plug for Python for Data Analysis. Though the title might sound a little bland, it's a good, practical summary of how to use pandas for the sorts of data analysis you often have to do in data science work.
